Adding fuel-up
 

I've been using Fuelly since 2010 and with that car, I was able to put in the miles sice last fill-up. I got a new car last month and see now that I have to enter the odometer mileage. Any way to change back to miles since last fill-up? When I get gas I zero the trip odometer and use that nmber which I write on the gas receipt. Every month or so I enter the information.

You have the choice to use either method. Click edit vehicle, and you can change it from odometer to trip :)
